“…The phospholipid compositions of the Bangladeshi strains of B. cereus in this study were similar to those reported for other bacilli (Bulla et al, 1970). The predominant phospholipids of the genus Bacillus are PE, PG and DPG, accounting for over 90 % of the total phospholipid, while the minor components are the alanine ester of PG and lysophosphatidylethanolamine (Lang & Lundgren, 1970).…”

The phenotypic adaptation of membrane lipids in seven strains of the food-poisoning bacterium Bacillus cereus, isolated from Bangladeshi rice, is reported in relation to their ability to grow under conditions of low water activity (a w ), reduced temperature and the presence of soluble rice starch. The strains have different membrane phospholipid head-group and fatty acyl compositions, and they display individual differences in their responses to both low a w and reduced temperature. The extent of the increase in anionic membrane lipids in response to low a w varies from strain to strain, is solute specific and in one strain does not occur. Growth is stimulated by the presence of soluble rice starch and results in a large rise in the proportion of diphosphatidylglycerol (DPG) at the expense of phosphatidylglycerol (PG), without any change in the proportion of total anionic phospholipids. Growth at 15 6C compared with 37 6C increases the proportions of DPG and phosphatidylethanolamine at the expense of PG. At the lower temperature there are changes in phospholipid fatty acyl composition characteristic of those expected to maintain membrane fluidity, including increases in the amount of total branched fatty acids and the anteiso-/iso-branched ratio, and a decrease in the equivalent chain-length, but there are strain differences in how those changes were achieved. In contrast to some other bacilli, there are persistent large increases in the proportions of unsaturated fatty acyl chains in phospholipids during growth at 15 6C.

A number of strains of Bacillus popilliae were examined for their ability to oxidize acetate. Some of these would not sporulate in vitro, and some were oligosporogenous. The ability to oxidize acetate varied widely among the strains tested. A culture derived from spores of the parent strain produced in vivo and one of the asporogenous strains derived from it failed to produce any significant levels of '4C02 from [14C]acetate. Oligosporogenous strains derived from the same parent culture all produced 14CO2 from both [1-14C] and [2-'4C]acetate but at relatively low rates. The highest rates of acetate oxidation were observed with three strains which did not produce spores in vitro. When cultured under appropriate conditions, one of these strains displayed a secondary growth response concomitant with a decrease in the titratable acidity and an increase in the pH of the medium. The data indicate that B. popilliae has a complete citric acid cycle but that the activity of the cycle is strongly repressed in wild-type strains under the usual conditions used for in vitro cultivation.

“…Bacillus thuringiensis, an economically important control agent for insect pests, catabolizes glucose primarily through the Embden-Myerhoff pathway while a small percentage is utilized for biosynthesis through the pentose phosphate shunt (Bulla et al 1970(Bulla et al , 1971Nickerson et a!. 1974).…”

Fermentation during growth and sporulation of Bacillus thuringiensis HD-1

During growth in a glucose‐tryptone‐mineral salts broth, B. thuringiensis HD‐1 Produced lactate, pyruvated, acetate, acetoin, and poly‐beta‐hydroxybutyrate (PHB). Based on the type and sequence of products found, all or part of the acetate appears to have been produced via the 2,3‐butanediol cycle. PHB was produced and utilized during spore formation and may have provided energy for that process.
